After-running time PnL
During the start phase, the pumps may repeatedly switch on and off for a long time, espe-
cially with solar and heating systems with long hydraulic system lines. This response can be
reduced by using a speed control or increasing the pump after-run time.
Depending on the selected program each output can be allocated an after-running time,
except mixer outputs.
Example
: After access to the sub menu PnL the display shows “t13”. That means, the
pump after-running time for output 1 is 3 minutes.
t1
means after-running time for output 1
After-running times (t1 to t5) can be
allocated to outputs A1 to A5
depending on program
.2 is the after-running time
Setting range: .1 to .9 (10 to 90 sec)
or 2 to 9 ( 2 to 9 min)
ex works = 0
For programs 112 and 113 additional settings are
possible in this sub menu PnL:
tc
... Cycle time, setting range: 0 to 90 min
(tc0 to tc9),
ew
: tc 3 (30 min)
tr
... Run time, setting range: 0 to 9 min
(tr0 to tr9),
ew
: tr 2 (2 min)
tb
... Blocking time, setting range: 0 to 90 min
(Tb0 to tb9),
ew
